Drafters rush to wrap up Senate immigration reform language

The Daily Rundown's Chuck Todd takes a "deep dive" look into whether the policy and politics surrounding the immigration bill will allow it to pass in Congress. Executive Director of the Latino Partnership for Conservative Principles, Alfonso Aguilar, joins to discuss.

Drafters are racing to complete the text of a comprehensive immigration reform bill slated to be unveiled on Tuesday, with minor loose ends causing some in the Senate’s Gang of Eight to urge a delay to presenting the sweeping legislation.

But, with pressure growing after multiple missed deadlines for the completion of the reform bill, sources within the group tell NBC News that the proposal is still likely to be formally presented in a press conference tomorrow.

The Senate Judiciary Committee was expected to hold its first hearing on the legislation on Wednesday, but that has now been postponed to Friday. An additional hearing will be held next Monday as well.

Senate Republicans and Democrats have yet to be briefed on the legislation in their respective formal meetings. The bill includes the opportunity -- if certain border security criteria have been met -- for qualified undocumented immigrants to obtain probationary legal status for 10 years before becoming eligible to apply for a visa.

Republicans are expected to meet tonight at 5:45 pm to review the plan within their own conference. (Lead GOP negotiator Sen. Marco Rubio of Florida was originally scheduled to brief his colleagues last week, but lengthy discussion of pending gun legislation pushed the presentation off the agenda.)At noon on Tuesday, Republicans also plan to sell the plan to outside conservative interest groups.

Democrats have yet not scheduled an internal briefing but would likely share the bill with colleagues during a regularly scheduled Tuesday lunch meeting tomorrow.
